rr

Operands

rr r | rr (rr) | rr (ii+dd),r | rr (ii+dd)

The contents of B are rotated right one bit position. The contents of bit 0 are copied to the carry flag and the previous contents of the carry flag are copied to bit 7.

Variants

Every form of rr the assembler accepts. The cycles column counts clock cycles, written as taken/not taken for the conditional forms.
